Abstract

High maintainability becomes a fundamental requirement of most manufacturing products and system maintainability performance represents a key factor in many manufacturing fields. The paper focus on a procedure to obtain maintainability requirements of a complex system and compares the methods to achieve the best fitting. The first part of the paper focuses on maintainability allocation procedures: failure rate-based allocation method, trade-off of failure rate and design featurebased allocation method, fuzzy maintainability allocation based on interval analysis and time characteristic-based maintainability allocation models. The second part shows a case study on a generic system containing a redundant architecture with three different MTTR objective of the overall system in order to test the proposed method.
